■ Locating people and vehicle on a map displayed on the mobile device<br />

■ Finding someone or something. Person by skill (doctor), business directory, navigation, weather, traffic, room schedules, stolen phone, emergency calls<br />

■ Location-based mobile advertising<br />

■ Proximity-based notification (push or pull). Targeted advertising, buddy list, common profile matching (dating), automatic airport check-in, and payment<br />

based upon proximity (EZ pass, toll watch)<br />

■ Turn by turn navigation to any address<br />

■ Receiving alerts, such as on sale notification or traffic jam alert<br />

■ Requesting the nearest business or service, such as an ATM or a restaurant<br />

■ Asset recovery combined with active RF to find, for example, stolen vehicles or assets in containers<br />

■ GPS data for operators to dispatch emergency personnel to the correct location<br />

■ Resource tracking with dynamic distribution. Taxis, service people, rental equipment, doctors, fleet scheduling<br />

On-Board Diagnostics (OBD-II)<br />

■ On-Board Diagnostics, or OBD, in an automotive context, is a generic term<br />

referring to a vehicle's self-diagnostic and reporting capability. OBD systems give<br />

the vehicle owner or a repair technician access to state-of-health information for<br />

various vehicle sub-systems.<br />

■ OBD-II is a standard that specifies the type of diagnostic connector and its pinout,<br />

the electrical signaling protocols available, and the messaging format.<br />

■ Almost all of the automobiles produced today are required, by law, to provide an<br />

interface for connecting a diagnostic test equipment.<br />

There are five signalling protocols currently in use with the OBD-II interface. Any given vehicle will likely only implement one of the<br />

protocols.<br />

■ SAE J1850 PWM (pulse-width modulation - 41.6 kB/sec, standard of the Ford Motor Company)<br />

■ SAE J1850 VPW (variable pulse width - 10.4/41.6 kB/sec, standard of General Motors)<br />

■ ISO 9141-2. K-line and L-line. This protocol has an asynchronous serial data rate of 10.4 kBaud. It is primarily used in Chrysler, European,<br />

and Asian vehicles.<br />

■ ISO 14230 KWP2000 (Keyword Protocol 2000)<br />

■ ISO 15765 CAN (250 kBit/s or 500 kBit/s). The CAN protocol is a popular standard outside of the US automotive industry and is making<br />

significant in-roads into the OBD-II market share. By 2008, all vehicles sold in the US will be required to implement CAN, thus eliminating<br />

the ambiguity of the existing five signalling protocols.<br />

OBD-II provides access to numerous data from the engine control unit (ECU) and offers a valuable source of information when<br />

troubleshooting problems inside a vehicle. The SAE J1979 standard defines a method for requesting various diagnostic data and a list of<br />

standard parameters that might be available from the ECU. Following is a list of vehicle diagnostic information you can read from OBD-II. It<br />
